The Honda XBR 500 is a 500cc Japanese sports single motorcycle launched by Honda in 1985 in response to the Yamaha SR500. It is powered by a single-cylinder four-valve engine with the valves arranged radially (the Radial Four Valve Combustion Chamber, or RFVC). Displacing 498 cc and producing 44 hp, the engine, which originated from the Honda XR series off-road models, features a dry-sump, the oil being stored in a separate oil tank below the seat. The steel-braided hoses connecting the oil tank to the engine (clearly visible at the right-hand side of the motorcycle) became a strong visual element. 1985 1986 1987 1988 1989 85 86 87 88 89
